Answer:

336 feet²

Step-by-step explanation:

If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².

If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².

To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².

Hope this helped!

WILL MARK BRANLIEST PLZ HELP ASAP!!!
Brrunno [24]

ANSWER

I. The GCF of 6 and 16 is 3. FALSE

II. The LCM of 6 and 16 is 48. TRUE

III. 6 and 16 are both composite numbers. TRUE.

EXPLANATION

The GCF of 6 and 16 is not 3.

It is rather 2.

Factors of 6: {1,2,3,6}

Factors of 16:{1,2,4,8,16}

3 is not even a factor of 16.

The LCM of 6 and 16 is 48. This statement is true.

Composite numbers have more than 2 factors.

6 and 16 are both composite numbers.

Are rhesw ratios equivalent 6:2 and 7:3
morpeh [17]

Answer:

No, they are not equivalent.

Step-by-step explanation:

There are two ways to check this.

1. You can multiply the means and extremes. If the ratios are equivalent, they products of the means and extremes will be equal.

Multiply the means (2 and 7) and multiply the extremes (6 and 3)

14 ≠ 18

2. You could also check these by dividing them.

6/2 = 7/3

3 ≠ 2.3

Since neither one of the checks are correct, 6:2 and 7:3 are not equivalent.


I really hope this helps =)
